METHOD OF FORMING WATCHCASE-PENDANTS.

Specification of Letters Patent.

Patented Sept. 1'7, 190'?- To all whom it may concern:

Be it known that I, GEORGE A. DERFLER, a citizen of the United States,and a resident of Riverside, in the county of Burlington and State ofNew Jersey, have made and invented certain new and useful Improvementsin Methods of Forming Watchcase-Pendants, of which the following is aspecification.

My invention relates to an improved method of forming watch casependants, and more particularly to that kind or style thereof usuallyknown and referred to as antique, characterized by an oval-shapedenlargement in the center thereof, adapted to receive and contain theends of the bow.

The object of the invention is to devise a method to simplify andcheapen the construction, and particularly those antique pendantswherein the outer side or surface thereof is covered with gold orprecious metal, and which have heretofore usually been constructed ofwhat is known as filled gold; also, to devise a method wherein theresulting pendant will be of such construction or formation that it willpractically be solid, and particularly in the ends of the oval-shapedenlargement, wherein the ends of the how are contained. Usuallythesependants are constructed of sheet metal, the ends of theoval-shaped enlargement being recessed or indented to receive the endsof the bow, which recesses in the course of time, wearthrough,thereafter allowing said bow to swing and move loosely therein.

With these and other ends in view, the invention consists in the novelmethod hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 illustrates a blank in the formof a shell, adapted to form the outer covering for the pendant. Fig. 2is a plug or rod of base metal, and employed to form the interior orbody of said pendant. Fig. 3 shows the metal rod inserted in the shell.Fig. 4 shows in elevation, the rod and shell stamped up into a formapproximating that of the pond ant. Fig. 5 is a sectional view of thesame. Fig. 6 is a view of the pendant in its next stage of formation,and Fig. 7 a sectional view thereof. Fig. 8 shows the finished pendant.

Referring to the drawings, A represents the shell, preferably formed ofgold or other precious metal, forming in the finished pendant, the outercovering for the base metal body of the pendant. While I prefer to formthis shell of thin gold, it will of course be understood that it may beformed from filled gold, that is, a metal comprising two outer thinsheets of gold with base metal between them.

To form the body or interior portion of the pendant, I employ the rod B,preferably of brass or other base metal, which will nicely fiow underthe action of forming dies, this rod being of such a diameter as tonicely fit within the shell A, as illustrated in Fig. 3, and of somewhatgreater length, in order to form the hub O of the finished pendant, andover which hub fits the crown (not shown), said hub being uncovered orunprotected by precious metal, as the same in this type or character ofpendant, is entirely concealed within the crown.

After the shell A and rod B have been assembled, as above described,they are subjected to the action of a pair of suitable dies, not shown,whereby they are shaped, as illustrated in Fig. 4, that is,approximating the shape or form of a pendant, the hub B correspond: ingto the projecting end of the rod B of Fig. 3, the remaining portion ofthe article being covered by the shell A By means of suitable tools, aportion of the rod B is then drilled out, leaving an interior body orshell D, (Fig. 7), provided with solid oval portions D and hub O, and atthe same time, or subsequently, a groove or recess D is cut into thebase metal portions D for the reception of the winding crown, which asin ordinary cases, fits around the hub O.

The shell A which covers the body D of the pendant with the exception ofthe hub O, at any desired stage of its formation is provided with theindentations or recesses D for the reception of the ends of the bows,and as this portion of the shell is backed by the base metal D said endsof the bow are constantly provided with a solid bearing, even throughthe outer precious metal covering in time be worn through.

The end of the pendant, which is usually soldered or otherwise securedto the watch case center, is knurled or otherwise ornamented with thegrooves D to impart thereto a neat and finished appearance.

This method of forming a pendant is a comparatively cheap andinexpensive one, as it involves but little labor. Furthermore, the outercovering of precious metal is extended over those portions only of thependant which are exposed to view, and as the shell may be madeexceedingly thin, backed, as it is by a base metal body, a materialsaving in the cost of the finished pendant, is thereby effected.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is:

GEORGE A. DERFLER.
